\title{\nJava}
\author{David von Oheimb \\ Tobias Nipkow}
\maketitle

\begin{abstract}\noindent
  These theories define {\nJava}, a very small fragment of the programming 
  language Java (with essentially just classes) derived from the one given 
  in \cite{NipkowOP00}.
  For {\nJava}, an operational semantics is given as well as a Hoare logic,
  which is proved both sound and (relatively) complete. 
  The Hoare logic supports side-effecting expressions and
  implements a new approach for handling auxiliary variables.
  A more complex Hoare logic covering a much larger subset of Java is described
  in \cite{DvO-CPE01}.\\

and the conference version of this document \cite{NanoJava}.
